Sorts every reachable H3 cell into travel time rings around the nearest location: 0-15, 15-30, 30-45 and 45-60 minutes, for example, with no overlaps between locations.
The tool sends one /h3 search per location. If any of them fails, the whole run fails, whatever the Robust Mode setting: a missing location would make the answer wrong rather than smaller.
| Description | |
|---|---|
| Locations | The point layer to draw rings around, such as stores, depots or sites |
| ID | The field identifying each location in the output |
| Travel Mode | Any of the 13 transport modes the Custom tools offer |
| Departing / Arriving | Whether journeys depart from the locations or arrive at them |
| Time Zone | The time zone the departure or arrival time is in |
| Departing / Arriving Time | The departure or arrival time |
| Travel time (in minutes) | The maximum journey time. The limit depends on the resolution, as for H3 Custom. |
| Resolution | The size of the cells, from 4 (largest) to 12 (smallest). Defaults to 8. |
| Travel time interval (in minutes) | The width of each ring. It must divide the travel time exactly: 60 minutes with an interval of 15 gives four rings. Defaults to 5. |
| Fields To Keep [nearest location] | Fields from the Locations layer to copy onto each cell, from its nearest location |
| Output Layer | Where to save the output - must be in the project geodatabase |
The optional Transportation options, Search range, Snapping and Remove Water Bodies are described on Common parameters.
A polygon layer with one row per reachable cell:
| Field | Description |
|---|---|
Index_id | The ID of the nearest location |
h3_id | The H3 cell ID |
travel_time_mean | That location's mean travel time to the cell, in seconds |
band | Which ring the cell is in, 1 being the innermost |
band_label | The ring in minutes, for example 15 - 30 min |
Each cell is measured from the location that reaches it quickest. A travel time exactly on a boundary belongs to the ring below it.
